Satonaka Ikkou, a 16-year-old boy, is a first-year trainee at the Saienji Buddhist Temple. His parents sent him there to be trained by his grandmother, the Saienji Priestess. At the temple, he finds himself surrounded by beautiful female priestesses-in-training. Upon seeing a girl naked, Ikko gains the ability to transform into a super-monk, performing massive exorcisms for the good of the temple.
